CVE-2025-5697 Overview
CVE-2025-5697 is a SQL injection vulnerability in Brilliance Golden Link Secondary System through version 20250424. The flaw resides in the /reprotframework/tcCustDeferPosiQuery.htm endpoint, where the custTradeId parameter is passed unsanitized into a backend SQL query. Remote authenticated attackers can manipulate the parameter to alter query logic and extract or modify database contents. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse. The weakness maps to [CWE-89] (SQL Injection) and [CWE-74] (Improper Neutralization of Special Elements in Output).
Critical Impact
Remote attackers with low privileges can inject SQL statements through the custTradeId parameter, leading to unauthorized data access and potential integrity loss.
Affected Products
- Brilliance Golden Link Secondary System versions up to and including 20250424
- The /reprotframework/tcCustDeferPosiQuery.htm handler
- Deployments exposing the custTradeId request parameter to untrusted networks
Discovery Timeline
- 2025-06-05 - CVE-2025-5697 published to the National Vulnerability Database

Technical Details for CVE-2025-5697
Vulnerability Analysis
The vulnerability stems from unsafe handling of user-supplied input in the tcCustDeferPosiQuery.htm request handler. The custTradeId argument is concatenated into a SQL statement without parameterization or proper escaping. Attackers can append SQL operators, UNION clauses, or boolean payloads to manipulate query results.
Exploitation requires network access and a low-privileged account, but no user interaction. Public disclosure of the exploit details lowers the barrier for attackers attempting reconnaissance against exposed instances. Successful attacks can expose customer trade records, credentials, and adjacent tables sharing the database context.
Root Cause
The root cause is improper neutralization of special characters in the custTradeId parameter before it is used in a SQL query [CWE-89]. The application trusts client-supplied input and constructs queries through string concatenation rather than prepared statements with bound parameters.
Attack Vector
An attacker sends a crafted HTTP request to /reprotframework/tcCustDeferPosiQuery.htm with a malicious custTradeId value. The injected SQL is appended to the original query, allowing the attacker to read arbitrary tables, perform boolean-based blind extraction, or attempt time-based exfiltration depending on the underlying database engine. No verified exploit code has been published in a structured proof-of-concept repository, but technical write-ups are referenced in the GitHub Document Repository and VulDB Entry #311213.
Detection Methods for CVE-2025-5697
Indicators of Compromise
- HTTP requests to /reprotframework/tcCustDeferPosiQuery.htm containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the custTradeId parameter
- Database error messages or stack traces surfaced in HTTP responses from the reprotframework module
- Unusual response time deviations on requests carrying the custTradeId argument, suggesting time-based blind injection
Detection Strategies
- Inspect web server and application logs for anomalous URL-encoded payloads targeting custTradeId
- Deploy a web application firewall (WAF) ruleset that flags SQL injection signatures on the reprotframework URI path
- Correlate authenticated session activity with bursts of failed or syntactically unusual SQL queries in database audit logs
Monitoring Recommendations
- Enable verbose query logging on the database backing the Golden Link Secondary System and alert on syntactically invalid statements
- Baseline normal traffic volumes to tcCustDeferPosiQuery.htm and alert on volumetric spikes from single source IPs
- Monitor for outbound DNS or HTTP callbacks originating from the database host, which can indicate out-of-band exfiltration attempts
How to Mitigate CVE-2025-5697
Immediate Actions Required
- Restrict network exposure of the Golden Link Secondary System to trusted internal networks or VPN-only access
- Audit existing accounts and revoke unnecessary access to the reprotframework module until a patch is applied
- Deploy WAF rules to block SQL injection patterns targeting the custTradeId parameter
Patch Information
No vendor advisory or fixed version has been published in the referenced sources at the time of writing. Operators should contact Brilliance directly for remediation guidance and track the VulDB CTI ID #311213 entry for updates.
Workarounds
- Apply input validation at a reverse proxy or WAF to reject non-numeric or non-alphanumeric values in custTradeId
- Enforce least-privilege database accounts so the application connects with a role that cannot read sensitive tables or execute administrative statements
- Disable or firewall the /reprotframework/tcCustDeferPosiQuery.htm endpoint if it is not required for business operations
